Summary

This Russian study developed a testing method for evaluating the impact toughness of anisotropic polymer composites using micro-scale samples and an impact pendulum, finding that increasing loading velocity by 10,000 times produced the largest changes in impact toughness and deformation capacity. The method provides a way to assess the mechanical behavior of fiber-reinforced plastics under dynamic loading conditions.

A method for investigation of impact toughness of anisotropic polymer composite materials (reinforced plastics) with the help of CM model sample in the configuration of microplastic (micro plastic) and impact pendulum-type testing machine under static and dynamic loadings has been developed. The method is called “Break by Impact” (Impact Break IB). The estimation of impact resistance CFRP by this method showed that an increase in loading velocity ~104 times the largest changes occurs in impact toughness and deformation ability of a material.
